Показать описание
In this video, we will learn to expand cot(x+y) or you can say to prove the trigonometry identity cot(x+y) = (cot x cot y - 1)/(cot y + cot x)
Other topics of this video are:
Expansion of cot(A + B)
How to prove the identity cot(A + B) = (cot A cot B - 1)/(cot B + cot A)?
Formula for cot(x + y)
Formula for cot(A + B)
